Login plugin redirect_after_login doesn't work

Hello everyone,

the redirect_after_login in the login plugin (in login.yaml) doesn’t seem to work for me. I also tried the “process: display: pagename” thing in the login.md, but I’m always getting an error “Uupps. Seems like the page your trying to reach does not exist”
Strange thing: the redirect_after_logout works perfectly.

Anyone else having this issue or knows how to fix it?
